YB-FETCH(1)

💖 YB-FETCH(1) — the one where you get your blobs back 💖

okay so real talk, this is a page from the User Commands manual and it's literally all about the fetch command, and bestie, it is so good. buckle up 🎀

---

✨ NAME ✨

fetch — retrieve one or more blobs 🫶

---

🌸 SYNOPSIS 🌸

fetch [-p|--stdout] [-o|--output] [-O|--output-dir] [-h|--help]
<PATTERNS>

---

🦋 DESCRIPTION 🦋

okay so here's the vibe: fetch retrieves one or more blobs from the YubiKey. no cap, that's the whole job. 👑

You can pass it names and glob patterns — both are accepted, which is highkey iconic of it. every blob that matches gets written to a file in the current directory (or in OUTPUT_DIR if you set one), and the filename is the blob name. slay. 💅

Also important, and this is the part where you listen: use --stdout or --output when exactly one blob is selected and you need direct control over where the thing goes. periodt. ✨

---

🎀 OPTIONS 🎀

• -p, --stdout — writes the blob content straight to stdout. only valid when exactly one blob matches, so don't get cute with it 🙈
• -o, --output <OUTPUT> — writes the output to this file. again, only valid when exactly one blob matches 💖
• -O, --output-dir <OUTPUT_DIR> — writes the fetched files into this directory. default is the current directory 🗂️
• -h, --help — prints help. classic. helpful. we love her 🫶
• <PATTERNS> — the blob name(s) or glob patterns you want to retrieve. this is the main character of the command fr fr ⭐

---

🌈 EXAMPLES 🌈

Fetch a single blob to the current directory:

yb fetch secret.key

Fetch to a specific file:

yb fetch -o /tmp/key.pem mykey

Print to stdout (pipe-friendly):

yb fetch --stdout mypassword | xclip

Fetch all blobs matching a glob into a directory:

yb fetch -O ./restore '*.key'

like, the glob one? '*.key' with the quotes? chef's kiss 🔥

💜 SEE ALSO 💜

yb(1), yb-store(1), yb-list(1) — go read those too, they're friends of this page 🧚

---

ngl, the "only valid when exactly one blob matches" thing shows up twice in the options and it's not a suggestion. if you've got multiple blobs matching and you point --stdout at them, that's a you problem 😭

and that's the page!! 🌸 it's from yb, dated 2026-03, and yes it's technically YB-FETCH(1) but we're on a first-name basis now. mwah 💖🍓👑
